M/A-COM Technology Solutions has introduced a wideband 6-bit digital attenuator for broadband applications such as military radar & radio systems, test equipment and commercial microwave radio and satellite links. The digital attenuator is offered as both bare DIE, MAAD-011021-DIE, and in a 3mm PQFN package, MAAD-011021; and operates from DC-40GHz and DC-30GHz, respectively.

MACOM has claimed that this is the industry’s first DC-40GHz, 6-bit digital attenuator. The device provides up to 31.5dB of attenuation in 0.5dB steps with attenuation error typically less than ±0.5dB and industry leading phase accuracy of 4 degrees RMS error at 20GHz. The digital attenuator integrates TTL digital control and is fully matched across the bandwidth of operation which enables the customer simple and fast implementation.

Paul Beasly, Product Manager, M/A-COM Technology Solutions, comments: “The new digital attenuator offers the industry’s widest bandwidth 6-bit digital attenuator with the lowest phase variation performance available. In combination with the 3mm PQFN option, the product offers customers a high frequency, small size, digital attenuator solution for applications that demand the greatest accuracy performance.”
